EDIT: Some quick research proves if i tried to use this to power say a box fan, it would prove fatal, well to the transformer atleast. 110 volts ac with a typical 2khz.</p>Customer #401881 on COM-10201 - EL Inverter - 3vCustomer #401881urn:uuid:d06b9e54-62e5-49d2-510a-d9c30f08f6f62014-06-11T11:55:42-06:00<p>Just to confirm, the EL inverter - 3V is just the inverter nothing else?

I got this, and the El Sequencer and I&rsquo;m wanting to run at least 2 El wires around 6 inches (about 15cm) in length each. Do I run a risk of burning the inverter out?

This regulator uses resistors to control the output voltage; you could conceivably replace one of these resistors with a &ldquo;digital pot&rdquo; that will give the Arduino a mechanism to control the DC voltage to the inverter.</p>
<p>Note that you can still PWM the triacs on the Escudo / Sequencer; you won&rsquo;t get smooth dimming from off to full-on, but you&rsquo;ll get a bunch of steps (some stable, some flickering) which might suffice for what you want.</p>therealadrian on COM-10201 - EL Inverter - 3vtherealadrianurn:uuid:9d42ed7c-8395-c2c2-9343-8421e3552ef32013-09-15T01:26:23-06:00<p>I was interested in looking into ways to control the brightness of EL wire. After realizing that I could not PWM the triacs on the EL Escudo Dos, and then looking at the data sheet for this device it seemed pretty clear that by modulating the input voltage, I could control the AC output voltage and thus the brightness of the wire. Worked great with the bench supply. However, I now find myself trying to figure out the best way to get from the PWM output on a 3V Arduino to analog control of the voltage on the input of the inverter. Given that the inverter is a bit of a load, does anyone have any suggestions on how I could approach this? (Its too much power for an RC filter and an opamp, as the peak draw is a couple of Watts.)</p>khoyt on COM-10201 - EL Inverter - 3vkhoyturn:uuid:61f719b4-7c89-3d41-53f9-87012cfe3b122013-04-26T21:32:38-06:00<p>If you are looking for screws to mount this to your project, I found that 2-56 steel machine screws/nuts from your local Radio Shack (or what have you) work great.</p>Customer #423565 on COM-10201 - EL Inverter - 3vCustomer #423565urn:uuid:6d957326-cccb-8616-d198-4798e7078e9e2013-03-28T13:18:49-06:00<p>Hi, I have been looking at all the sizes of inverters for el wire and wondered what the smallest might be to power a small length such as maximum 1m but more like 50cm? I want to put it on some accessories but the inverter and battery needs to as thin and as small as possible but I&rsquo;m not sure if this exists - saw your forum and thought you might be able to help? Is it possible to make compact inverters to carry a CR2032 lithium battery (or equivalent frequency of 500-100 Htz for 100v).</p>

The red/black pair of wires is the INPUT. This is the side you hook to your 3v source.<br/>

From the test results described above, a single inverter might not be enough to light more than 20 feet at maximum brightness. So my question is, how would I go about increasing the power to the EL wire&ndash;do I use more than one inverter? If so, would I also need 2 sequencers? Or is there a way to connect 2 inverters to 1 sequencer (without destroying the sequencer), and, if so, how would I do that?

With 1 3m length of wire, driven properly, there is a small buzz coming from it, but nothing TOO noticeable.<br/>
It is possible to drive with 5v (we programmed the demo with a 5v FTDI basic), but the buzzing increases a bit.</p>RobertC. on COM-10201 - EL Inverter - 3vRobertC.urn:uuid:f9d6718f-77a1-0e6c-5190-fe17805005502011-01-06T11:47:16-07:00<p>Check the description above, I did some tests and posted the results.</p>Brian W Evans on COM-10201 - EL Inverter - 3vBrian W Evansurn:uuid:c5a89432-2c11-aa00-1acd-46661010ff842011-01-05T21:33:09-07:00<p>Definitely need to know the rated feet but also 2 other questions: how noisy is this guy and if I run it at 5v is the magic smoke going to escape?<br/>
